Serial No, 350,077. (No model.)

To aZZ whom it may concern.-

Be it known that l, MINOR b. COLEMAN, of Canon City, in the county of Fremont and State of Colorado, have invented certain new and useful Improvements in Bailing-Presses; and 1 do hereby declare the following to be a full,clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification. 7

My invention relates to an improvement in bailing-presses; and it consists in the arrangement and combination of parts, which will be fully described hereinafter.

The object of my invention is to provide a baling-press in which hay and materials of all kinds can be compressed into bales, and to construct it as hereinafter shown and described, tor the purposes set forth.

Figure 1 is a side elevation of a press which embodies my invention. Fig. 2 is a plan view of the same, the top of the power end of the machine being removed, so as to show the operating parts. Figs. 3, at, and 5 are detail views of dilterent parts. Fig. 6 is a detached perspective of a follower-block which is placed between the bales. Fig. 7 is an end view of the exit end of the baling-chamber.

A represents the bottom bed-piece, which extends from the power end under or a part of the way under the baling-chamber, andB the top piece which forms the upper part of the power-frame and extends from power end to the end ot' the jack-frame. The balingchamber (1 may either be placed on the bottom bed-piece or may be bolted or otherwise securely fastened to it, and this baling chamher is secured at its inner end by means of the truss-rod D to the jack-frame atone end, the rod being arranged above the pitman. The operating'shaft 1* which. is driven by means of a sweep or other suitable power, extends vertically through the top piece B, and has secured to or cast integrally therewith between the pieces A and B the slotted arms F. In the slots in these arms F are placed the two laterally-moving pins or bolts G, which are forced outward toward the outer ends of the slots by means of the curved piece or cam U, secured to the under side ot the top piece B. The heads of the pins G project just far enough above the tops of the arms F to strike against this cam as the arms are caused to revolve by the shaft E, and thus move the pins from the inner ends of the slots to the outer ones, so that each pin will be in position to engage with the outer ends of the pitman as the arms sweep around.

When the compression of the hay in the chamber 0 first begins. but little power is required; but as the compression continues a greater amount of power is required and the pins are alternately caused, by hearing against the outer end of the pitman, to move toward the inner ends of the slots in order to bring the power nearer the center of the motion, where the greatest power is required.

The inner end of the pitman I is loosely connected to the adjacent end Of the sliding bar I, so that the Outer end of the pitman will follow the circular motion of the arms F, and the outer end of the pitman is provided with a shoulder at its outer end, as shown, so that when one of the pins strikes against it it is held in contact therewith until the whole power of the arm has been exerted through the pin upon the pitman, when the pin slips off.

In order to cause the outer end of the pitman I to always return to position after having made its stroke, so as be struck by the next pin which sweeps around, there is pivoted upon the bottom piece A a lever J, which is curved at its inner end, as shown, and against this curved portion of the lever the ends of the lower arms F strike, for the purpose of causing this lever to partially turn upon the pivot, which passes through its in nor end. As this lever J turns upon its pivot its movement is communicated through the connectingrod K. to the lever L, also pivoted upon the bottom piece A. This lever L extends entirely aeross the bottom piece A and projects beyond the opposite side, and has connected to its projecting end the rod M, which has its Opposite end connected with the outer end of a lever N, and with the pitman, by means of a rod 0. The pivot N upon which the lever N turns, passes through the slot in its inner end, so that the lover can move back and forth, and thus conform to the m ovemeut.

of the outer end of the pitman 1., Afterthe pitnian has made its whole stroke and the pin G has slipped off its end the lower arm F in its continued movement strikes against the curved part of the lever J and causes it to turn upon its pivot and exert a pressure through the rod K upon the lever L, and this lever L, through the rod M, causes the lever IO N, through the pin 0, to move the pitman back into position. The rebound of the com pressed material when the pin slips off the outer end of the pitman I is such as to cause but very little pressure to be exerted to return the pitman to position; but this rebound will not always return the end of the pitman to the same position, and hence it becomes necessary to provide a mechanism to always move the end of the pitman I back to its starting-point, where the pin 0 will strike against it. In order to limit the rebound and at the same time to assist in guiding the pit man I back into position, the slot-ted guide P is provided, which is placed between the bot- 2 5 tom and top sills A B and braced in position by the brace Q, which has its outer end rigidly secured to the jackframe. Through the pitm'an I is passed a vertical pin R, which strikes against the guide P and prevents the outer end of the pitman I from being moved back beyond a certain point.

In order to always guide the outer end of the sliding bar I in its movement and to cause it to always move in a direct line with the billing-chamber, there are placed between the bottom sill A and the inner end of the top piece B the two grooved parts S, and passing-through the outer end of the sliding bar I is aguiding-pin T,whioh also passes through 40 the disks U, placed above and below the adjacent ends of the pitman and the sliding bar 1, so as to keep it perfectly steady in its movements. These slotted pieces S, which form the guides for the connected ends of the pitman 5 and sliding bar, form what is known as the jack-frame. The pitman and the sliding bar are connected by the pin which moves in the jack-frame and which causes theinn or portion of the pitman to work in a direct line with the baling-chamber, making it easier for the horses to get overthe crossing, reducesthe friction, and enables a stronger and bet ter construction to be produced than where only one pitman is used. The jack-frame and the haling-chamber are connected by the tension or truss-rod D above their centers, which serves to hold the jack-frame and baling-chamber rigidly together and balances the opposing force produced in compressing the material.

g The baling-ch-amber C is constructed as shown, and its outer ends are connected and made slightly adjustable in relation to each other by the rods or bolts V, upon which the doors V are pivoted. By loosening or tightening the nuts on the ends of the bolts V the top and bottom ends of the baling-chamber can be brought nearer together or allowed to be moved further apart, according to the amount of tension desired upon the bales. Between the bolts V and the ends of the doors V on either side are yokes K, through the ends of which pass bolts which extend across the top and bottom of the chamber, and by means of these yokes the doors \V are forced inward or allowed tomove outward, thus requiring a varied amount of force to push the bale through and out of the end of the chamher. The doors \V are provided with a longitudinal rib with which the yokes engage as they are moved in and out on the end of the chamber, and the springing of the doors V at their ends 'isregulated by the longitudinal adjustment of the yoke X upon the end of the balingchamber by reason of this yoke engaging the longitudinal flanges 3 upon the sides of the said doors. It is found that the best results are obtained by placing the yoke about one-third the length of the doors. The 'doors are so arranged as to leave a space above and below for the upper and lower wire baleties to pass without obstruction, and are recessed in the center to give space for the middle wire to pass.

Just forward, at the point at which the plunger stops at its full-stroke, there are placed in the bottom of the chamber 0 the two wedgeshaped lugs Y, which have their square ends turned toward the outer end of the balingchamber, so that when the compressed material is forced over them they assist in holding the bale at its lower edge, so as to prevent any backward movement at this point. As the material is forced forward by the plunger, it passes up the inclined sides of, these lugs and then drops down behind their outer ends. These lugs may be made to form the heads of bolts which secure the baling-chamber upon the top of the bed-piece A.

The follower-block Z is so constructed as to almost fill the chamber at its upper and lower ends; but in the middle of the space, where the tension-doors work, it is cut out to give space for the tension-doors to operate, as shown in Fig. 6. These follower-blocks are put into the press through the feed-space and pass through the baling-chamber, serving to separate the bales and to permit the wires to pass through the grooves in each side of the follower-blocks for the purpose of tying the bale before it is driven out. The advantage of this cutting away is that it prevents the follower-block from working wholly to one side, thus allowingthe opposite side to become too open,so that the material willcrowd in the space between the plunger and the side of the press,clogging the space where the wires pass through. The upp r and lowerends,if made to nearly fill the space in the chamber, serve to hold the ends steady, and the space where the doors Work need not be so large as to admit of the compressed material crowding or filling the space.

The plunger is provided with two grooves in its opposite sides, and in these grooves the retainers A operate. These retainers A are pivoted in suitable bearings B upon the sides of the inner ends of the baling-chamber, and the forward ends of the retainers are placed about one and onehalf to two inches back of the end of the plunger when forward its full stroke. Pivoted in the inner ends of the bearings B are the triangular cams G, which operate the retainers A through the forward motion of the plunger. As the material is forced forward in the baling-box the forward ends of the retainers A are thrown outward and their rear ends inward, which strike the outer sides of the cams G. The retainers remain in this position until the inner ends of the cams are engaged by the rear ends of the grooves in the plunger, which force them outward and the forward ends of the retainers inward in contact with the material for the purpose of preventing it from moving backward with the follower.

Pivoted in the opening in the top of the baling chamber and just beyond the hopper is a triangular folder I), which extends downward into the top of the chamber a suitable distance. The pivotal rod of the folder e2 tends out on each side of the chamber, and to each of the bent ends of the rod is secured a weight F. As the material is driven forward into the chamber by the plunger it strikes the under beveled side of the folder and causes its in ward edge to turn up, lifting the weights on the ends of the rod to which the folder is rigidly secured. \Vhen the plunger is withdrawn, the weights cause the folder to turn down into the chamber, and thus turn or fold down the material that may project back beyond the opening in the top of the chamber. The next material forced inward by the plunger causes this folded-down material to be held or folded in, thus making a smooth bale.

The rear end only of the hopper G extends upward the desired height,bnt an adjustable side board H may be applied to either one of the sides of the box or hopper, so as to raise that side to the same height as the rear end, and thus allow the material to be baled to be fed in from either side. By cutting away the front end and side the lifting of the material so high is avoided and the material can be raked from a platform or pile into the box, the side board and rear end preventing the material from falling off the box or hopper. Hinged or otherwise loosely connected to the top edge of the rear end of the plunger is a plate X, which has its front end Y turned downward, so as to catch over the front end of the plunger. Placed between the top of the plunger and the under side of this plate is a short chain or rod Z, which allows the front end of the plate a slight upward movc-. ment. The plate is preferably made of boiler iron and has its edge beveled to a knife or sharp edge. By means of a spring this plate or turned-down portion rests against the upper edge of the solid end of the plunger. The spring forces the front end of the plate upward and the rod or chain limits its upward movement, so that it will never raise so high as to prevent it from entering the rear end of the chamber as the plunger is forced downward. If the hay is not properly adjusted in the feeding-space and gathers too thickly on the top of the plate, the flanged end is forced down and prevents the plunger from sticking fast by becoming wedged in the chamber. The flange Y covers the space between the plunger and the inner side of the baling-chamher and prevents the hay from passing in between the plunger and the inner side of the bailing-chamber, as it would otherwise do.

Although only two arms F are here shown projecting from the main driving-shaft, to which the sweep E is attached, three or more sets of arms may be secured to the shaft, so as to cause the plunger to give any desired number of strokes to each revolution of the shaft.

By means of a baling chamber of the construetion herein shown and described the hay is forced continuously through the press at every stroke of the follower.

The baling-chamber is preferably made of a length sufficient to hold three bales and the tension-doors act as a brake to hold the end bale from passing out, except as it is driven out by the pressure of each successive feed.

Having thus described my invention, I clain1 1.
